    <p>A simple solution would be to change the order of your if conditions so you first check whether an array element is null, and if so, initialize it by assigning a new <code>Person</code> instance like so: <code>people[i] = new Person()</code></p> <p>Fixed code:</p> <pre><code> if(people[i] == null){ people[i] = new Person(); // ADD THIS LINE TO FIX THE NPE people[i].name = personName; Jobs tempNode = new Jobs(); tempNode.typeOfJob = newJob; tempNode.next = null; people[i].jobs = tempNode; break; } else if(people[i].jobs != null){ if(people[i].jobs.compareToIgnoreCase(newJob) == 0){ //if the person has been added, check to see if the job has //already been added Jobs currentNode = people[i].jobs; while(currentNode.next != null){ //if the job has already been added, break if(currentNode.typeOfJob.compareToIgnoreCase(newJob) == 0){ break; } currentNode = currentNode.next; } //if the job has already been added, break if(currentNode.typeOfJob.compareToIgnoreCase(newJob) == 0){ break; } else{ Jobs tempNode = new Jobs(); tempNode.typeOfJob = newJob; tempNode.next = null; people[i].jobs.next = tempNode; } }//end if the job has already been added } </code></pre> <p>You need to do this because the elements of the Array you created with <code>Person people[] = new Person[N];</code> are still null, so the memory for the properties you are trying to access is not yet allocated. Java doesn’t have anything similar to C structs, so your <em>struct</em> is just a simple Java Object, which needs to be instantiated with new, before its fields can be accessed.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
